The volume of a cube is: V = s^3

  • Faman39
last one, right?
Faman39
  • Faman39
No, i think i m wrong
baldymcgee6
  • baldymcgee6
you are wrong.. :) v = s^3 144 = s^3 s = cbrt(144) V_pyramid = (area of base)(height)*(1/3)

So you think it is third one ?
baldymcgee6
  • baldymcgee6
nope..
Faman39

volume of pyramid = 1/3*breadth*breadth*height breadth and height are same in this case and is equal to--- since side cube = 144 x^3=144 x=5.24
ghazi
  • ghazi
now you can do it
ghazi
  • ghazi
volume = 0.333*5.24*5.24*52.4 since it's a cube so breadth= height
ghazi
  • ghazi
@Faman39 now?
Faman39
  • Faman39
You divide the 144 with 3, right?
ghazi
  • ghazi
it will be 47.923 = 48
ghazi
  • ghazi
no, i found side of cube by this formula \[(side)^3=144----side=\sqrt[3]{144}\]
ghazi
  • ghazi
and volume of pyramid here, \[V=\frac{ 1 }{ 3 }*side*side*height\] and side=height (given) and 1/3=0.3333
ghazi
  • ghazi
clear? @Faman39
